Betta Fish Care


Bettas are carnivorous and can be fed flake or pelleted food. Please refer to the food packaging for feeding guidelines so you do not overfeed.

Bettas also enjoy eating frozen or freeze-dried bloodworms, tubifex worms, mosquito larvae and daphnia. When feeding Bettas frozen food, please make sure that it is thawed.
